To (ZZZ whom it may concern:

Be it known that I, ALLEN E. OSTRANDER, residing at Ridgewood, Bergencounty, New Jersey, and being a citizen of the United States, haveinvented certain new and useful Improvements in a Dumping-Car, of whichthe following is a full, clear, and exact description, such as willenable others skilled in the art to which it appertains to make and touse the same, reference being had to the accompanying drawings, whichillustrate the preferred form of the invention, though it is to beunderstood that the invention is not limited to the exact details ofconstruction shown and described, as it is obvious that variousmodifications thereof within the scope of the claims will occur topersons skilled in the art.

In said drawings:

Figure 1 is a side elevational view of the car forming the subjectmatter of the present invention, showing in dotted lines the position ofthe wheels of a truck;

Fig. 2 is a transverse sectional view of a little more than half of thecar, the section being taken as indicated by the arrow 0, at 2-3 of Fig.1;

Fig. 3 is a similar view, the section being taken along the same line,but looking in the direction indicated by the arrow 6,-

Fig. 4 is an enlarged sectional view partly broken away, the sectionbeing taken on line 1-4 of Fig. 1 looking in the direction indicated bythe arrow;

Fig. 5 is an end elevational view;

Fig, 6 is a plan view of one portion of the car extending from an endsill and the side wall partway beyond the middle of the car and beyondthe center sill;

Fig. 7 is a longitudinal sectional view of an end portion of the carwith the upper portion of the side wall broken away, the section beingtaken on line 7-7 of Fig. 4, looking in the direction indicated by thearrow;

Fig. 8 is a lon itudinal sectional view, the section being ta enapproximately on line 8-8 of Fig. 6.

The object of the invention is to roduce a maximum capacity caravailable or general service in hauling articles of considerable lengthand possessing the advantage of being adapted for use in carryinggranular material, coal, etc., which can be dumped in the pockets nowprovided.

In the coal service and more especially in the anthracite region, it iscommon practice to run coal cars on trestles over coal pockets and dumpthe coal through bottom doors into such pockets. This practice resultedin the development of the self-clearing type of hopper car, known ascenter dump cars, designed to discharge all of its lading centrally ofthe car and between the rails. On western roads a type of gondola carwith bottom doors, known as outwardly dumping doors, adapted todischarge lading outwardly and away from the rails, has been developed.These outwardly dumping doors extend, in some instances, the entirelength of the car body and as the cars are frequently much longer thanthe pockets, such cars are not commonly available for use in theanthracite region where the lading is to be dumped outwardly unless atipple is employed or but a portion of the lading is dumped at a time.

To produce a maximum capacity car which will possess the advantages ofthe gondola car and the self-clearing hopper is the object of thepresent invention, which contemplates the employment of outwardl dumpingdoors over the trucks of the car and center dumping doors to dischargethe lading from the middle portion of the car, Which middle portionextends downwardly below the plane of the bottom of the car over thetruck portions, thereby greatly increasing the carrying capacity of thecar. With that object in View and to overcome difficulties inherent incars of the gondola type with outwardly dumping doors extendingthroughout the length thereof, the present invention provides a car bodyof maximum capacity which can be dumped into the pockets commonlyprovided in the anthracite region, while possessing the advantages ofthat type of car employing outwardly dumping doors throughout itslength.

To effect this desirable result, outwardly dumping doors are provided inthat portion of the car body over the trucks and center dumping doors inthat portion of the car body intermediate the trucks, which doors areoperated, respectively, by a plurality of longitudinally extendingoperating shafts and a transverse shaft at each side of the middle ofthe length of the car body so that approximately one-half of the ladingmay be dum ed into-a single pocket. at one time, after which the car maybe again spotted and the remaining portion of the lading discharged intosaid pocket. Associated with the longitudinal and transverse shafts aredoor-operating devices hereinafter more specifically referred to.

Referring to the parts, 1 indicates the wheels of the truck, 2 thecenter sills, which preferably extend throughout the entire length ofthe car body, though this is not absolutely essential to the invention,but Where employed in the middle portion of the car the sills are unitedby top cover plate 3 and covered by the conventional shedding crown 4,which may be of any type of construction preferred and preferably thecenter sills extend beyond the end wall 5, as best shown in Fig. 7. Theprincipal side wall 6 is of plate girder construction provided with atop chord 7 which is shown in section in Fig.2 and is of the shape incross section which has been found best adapted for application to carswhich are sometimes dumped on the tipples in which the entire load ofthe car is dumped at one time. The bottom chord 8 is preferablyangle-shape in cross section and the. side walls are connected and tiedtogether by the usual cross tie channel 9, connected with the side walls6 by means of the knee braces 10,,one of which is shown in Fig. 2.

A bolster 12, shown in dotted lines in Fig. 6, in elevation in Fig. 4and in section in Fig. 7 is built up and comprises the conventionalbottom plate 13, top plate 14 and the diaphragms 15, which latter are ofpeculiar construction, being formed from a pressed plate deeper in thevicinity of the center sills than at the outer ends where saiddiaphragms are connected to the side stakes 16. Bolster diaphragmsincline upwardly and outwardly from thelongitudinal center line of thecar, as shown in Fig. 4, .and are provided with the flanges 18 throughwhich said diaphragms are connected by means of the rivets 19 andbetween the meeting faces of the adjacent bolster diaphragms there areinterposed heavy T- sections 20 extending above the center sill fromeach end of the shedding crown or ridge 4 to the adjacent car end, towhich the door-operatin brackets 21 are riveted, as shown in Fig. andupon these brackets the doors 22 are supported by the usual strap hinges23 or other equivalent supporting means. The T-section extends throughthe bolster, as shown in Figs. 4, 6 and 7, from the end wall 5 to whichit is connected by means of the knee braces 25 to the cross bearer 26'ateach end of the car and terminates preferably at such cross bearers, assho'wn in Fig. 8, and the diaphragms of the cross bearers are pocketed,as are the diaphragms of the bolsters, to accommodate -therebetween thedepending vertical leg of the T-section 20, through which depending legand the outstanding flanges of the cross bearer diaphragms and thediaphragms of the bolsters, rivets extend to form a rigid structure.

The bolster being of the depth best indi cated in Fig. 4 permits placingthe hinges of the doors 22 at such an altitude that when the doors aredropped to dump that portion of the lading over the trucks, such doorswill have a considerable drop as indicated in Fig. 4, thereby providinga maximum discharge opening for lading above the trucks, and as thefloor plate 27, which extends longitudinally from the end wall to thecross bearer 26, is relatively narrow, approxim itely the entire loadabove the trucks can be dumped through the outwardly dumping doors thereprovided.

The usual bolster center filler casting 28 and center bearing plate 29are employed, as shown in Fig. 4.

Intermediate the cross bearers 26, twin hoppers are provided, one pairadjacent each set of cross bearers 26 extending to the middle of thecar, as shown in Fig. 8. At the middle of the length of the car, tieplates 30 extend from the side wall 6 inwardly and to the center silland serve the double function of reinforcing the body of the car andassist somewhat in dividing the lading when it is desired to dump suchlading from either end portion of the car. These plates 30 are connectedto the side walls by means of the angles 31 riveted to the side wallsand extending downwardly within the car body nearly to the bottom ofsuch plates. Along the bottom edge portion of the plates, stiffeningangle 32 is secured which stiffening angle extends, as shown in Fig 3,transversely across the car, is connected to the bottom"fianges of thecenter sills 2 and serves as a cross tie in the car body construction. I

Extending obliquely downwardly and longitudinally of the car from theplates 30, are the fixed hopper slope sheets 34 reinforced by the angles35 extending transversely thereunder and to the fixed hopper slopesheets are secured the hopper dooroperating devices indicated generallyby the reference character 36.

The opposite ends of the hoppers, that is the ends nearer the trucks,are formed in part by the cross bearers 26 and the relatively narrowfixed slope sheets 38 along the bottom edge portion of which fixed slopesheets are secured reinforcing angles 39 to which the door hinge butts40 of the inclined hopper doors 41 are secured, so that the door side ofthe hoppers is formed in part, each, of the cross bearers, narrow fixedslope sheets and the doors, and as the four doors of the twin hoppers oneach side of the center sills are of substantially identicalconstruction, description of one will answer for all. The side hoppersheets 42 on the inner sides of the hoppers are riveted to and dependbelow the sill 2, as shown in Figs. 2 and 8, and there is secured tothese sheets the conventional door stops, or door strips, 43 shownpartlyin elevation and partly in section in Fig. 2. The outer sidehopper sheet 42 overlaps the lower chord 8 of the side plate girder, asshown in Figs. 2 and 3, and is connected therewith by suitable rivetconnection, extending thence downwardly for part of its depth parallelwith the fillers 5O interposed between the side stake extensions andouter side hopper sheets, as shown in Fig. 2. Intermediate the length ofsaid side hopper sheets, other extensions of the stakes comprise angles51, see Fig. 3, which are connected with the bottom chord 8 by means ofthe knee brackets 52 for the purpose of stiffening and supporting saidside hopper sheets.

The cross bearers 26 are provided w1th top and bottom cover plates 56and 57 re- I spe'ctively, for -well understood purposes, and the topcover plate is of greater Wldth than the top flan e of the cross bearerto,

which it is secure so as to afford a stop for the outwardly dumping doornext ad acent to such cross bearers, and, as ls'common in this ty e ofcar door, stops 60 are secured to' the b0 ster diaphragms and the crossbearer diaphragms to limit the opening movement of the doors.

The door-o crating mechanism comprises a plurality o longitudinallyextending operating shafts at each end of the car and a singletransversely extending shaft at each side of the longitudinal center ofthe car, and these shafts may be connected to synchronize the operationof all of the doors, if desired, but as the mechanism for accomplishingthis forms no part of the present invention, it is not here lllustrated.

In the structure illustrated, the shafts 7 extend longitudinally throughthe end wall of the car to the side stakes 16, past the side stakes 16and upon the filler 50 there are secured door shaft brackets 71 toreceive the inner ends of the shafts 70..

Suitable winding chains and door-locking means are best shown inconnection with the shafts 70, are provided for lifting the outwardlydumping doors over the trucks, and connected with the shafts 73, aresuitable door-operating devices, indicated generally by the referencecharacter 36, WhlCh are connected to the bars 74 extending across thecar beneath the doors of both hoppers and are connected thereto so" asto operate the doors together, the inclined hopper door 41 being shownin open position with relation to the hopper at the left-hand side ofthe center of the car, Fig. 1, and in closed position at the right-handside hopper of that figure.

As it is desirable, as hereinbefore indicated, to provide the maximumopening for the outwardly dumping doors above the trucks, thedoor-supporting T-section 20 is carried at some distance above the upperlevel of the channels 2 of the center sills, and said T-section issupported at one end by the end wall, at the opposite end by theadjacent cross bearer and intermediate its ends by the bolster andbetween the bolster and end wall and between the bolster and adjacentcross bearer additional supporting brackets 80 are provided, as bestshown in Fig. 7, which brackets rest upon the center sills, extendthence upwardly and lap, and are securely riveted to, the depending legof the T-section 20, thereby providing additional supporting meanstherefor within the zone of the outwardly dum ing doors.

As shown in Figs. 4, 5 and the outwardly dumping doors incline upwardlyand outwardly from the longitudinal center of the car above the trucks,thereby providing an incavated bottom portion with dumping doors abovethe trucks.

The end wall of the car is reinforced by means of the angle 81, shown indotted lines in Fig. 5 and in section in Fig; 7, which an 'le extends,as shown by dotted lines in Fig. 5, upwardly and outwardly from theregion of the center sills'to and above the tension chord 8 of the sideplate girder, above which it is crimped, as shown in dotted lines inFig. 5, and to which it is riveted, while along the bottom edge of theend wall is another reinforcing angle 82 which is riveted to the centersills, as shown in Figs. 5 and 7. The ush-pole pockets 83 arefpositionedwithin t e zone of the reinforeement formed by the bottom chord 8 andthe transversely extending angle 81, as best shown in Fig. 5, therebyproviding the necessary -ri idity when the push-pole pocket is use inpoling thecar.

Other details of construction, conventional in cars of this generaltype, are shown but are not described in 'detail as they form no part ofthe present invention, WhlOll is designed to provide a maximum capacit'car bod" which will be self-clearing an which, ue to arrangement of theparts, will be unusually rugged and adapted' for rough serviceconditions.

It will 'be observed that when functioning. as doors the outwardldumping doors are all obliquely dispose and the center dump doors are inlower planes than the others, that the center of gravity of the load islow and the door-openings, when the doors are in open position," arelarge enough to permit quick discharge of all lading.
